Out-of-touch old gamer looking for 3090-compatible components - eviltoast

Title pretty much tells you all you need to know about my situation. In a turn of events tonight I’ve been gifted a used but working EVGA 3090 card to replace my seven year old 1070.

My current system hardware specs are:

CPU: AMD Ryzen 9 5900X 12-Core (upgraded from Ryzen 5 last year)

GPU: MSI 1070

MoBo: MSI MAG B550 TOMAHAWK

PSU - Corsair CX-550 550 Watt

x4 8GB Installed Memory

I also have a 2tb SSD drive with my OS and games installed, and 4 8tb HDD for media.

My main concern is with needing to replace my MoBo with a x3 PCi board and worries about my PSU not being powerful enough. I’m not particularly worried about my tower is a Phanteks Enthoo Pro PH-ES614PC_BK.

Thanks in advance!

    don’t need to touch anything except the psu. the rest of your rig will keep up fine. that phanteks has official support for up to 340mm long cards without the hard drive cages (you will likely need to remove those), and the EVGA FTW3 3090’s were 300mm cards on the dot.

    absolutely the fucking do not try to run a hungry 3090 off a 550W CX supply. the infamous 30-series transients will trip that poor thing constantly. buy a 750w or ideally a 850-1000w fully modular unit from SeaSonic, Corsair, or EVGA.

      My 850w seasonic X powersupply tripped on a 3080ti. I got a 1000w Seasonic and that seemed to fix it.

        yeah the 30 series power management was not great. i doubt that was ever the PSU’s fault- if anything seasonic’s more sensitive OCP would have exacerbated the problem lol

          Yeah, was annoying, but the PSU was already halfway through it’s useful life while chips have been ballooning in power requirements. I gave it to a friend and hope to keep this PSU longer. Though I plan on keeping my current hardware for a number of years as improvements have been pretty iterative. :p

            yeah the PSU market has sure changed. 1000W used to be insane, now it’s just normal for high end builds lol.

            if you’re running a 3080ti you’re definitely good on hardware at least for another 3-4 years. I managed to stretch my old 970 almost 6 years, I can’t imagine current top-end hardware will age any worse than that.
